SNOW-PLOVV.

Application filed January 22, 1913.

To all whom it may concern:

Be it known that I, ELI CLAYBORNE, citizen of the United States, residing at Hot Springs, in the county of Garland and State of Arkansas, have invented certain new and useful Improvements in Snow-Flows, of which the following is a specification.

This invention relates to snow-plows.

The primary object of the invention is to provide a plow disposed to be attached to the pilot of a locomotive with means for melting or removing snow and ice.

A further object of the invention is to provide a construction of this character which may be conveniently transported and readily assembled on the pilot of the locomotive.

Another object of the invention is to provide a plow with a radiator for melting or removing snow, which will receive steam from the locomotive, the plow being of such design and dimensions as to completely shield the lower part of the locomotive.

A still further object of the invention is to provide a construction in which access to the radiator may be readily had when it is desired to properly drain and repair the same.

Another object of the invention is to provide a device which may be readily coupled to the pilot, the connection between the steam supply and the radiator being made after the device is coupled to the pilot.

In the drawings: Figure 1 is a side elevation showing the device arranged on the pilot of a locomotive; Fig. 2 is a top plan view; Fig. 3 is a section taken on the line 33 of Fig. 2; Fig. 4: is a rear elevation, the device being shown as supported upon trucks upon which it is moved when it is assembled on the pilot of the locomotive; Fig. 5 is a detail view of a portion of the radiator; Fig. 6 is a detail view of one of the shaft brackets which are disposed on the base of the plow and which receive the shafts of the trucks; Fig. 7 is a detail View of one of the attaching plates.

In the drawings, 10 designates the plow, the front shield or plate 11 of which tapers longitudinally to conform generally to the base outline of the pilot. This shield preferably comprises two plates 13 and 14 which are secured together at 15. The plates are concaved, and their meeting edges are cut circular to form the projecting points 16 and 17 Specification of Letters Patent.

Serial No. 743,458.

Secured to the rear wall of the shield adjacent its edges is a frame 18. This frame is connected at its upper end by the yoke 18, which extends transversely of the plow, being bowed-centrally to accommodate the pilot of the locomotive. This yoke is supported by truss rods or struts 18 which are connected to the upright members of the frame, thus providing an effectual compact supporting frame. radiator 19 which is formed in three sections, the end sections 20 and 21 and the intermediate section 22. The radiator comprises a series of tubes 23 which at their terminals 24 are connected with the curved conduits 25. These tubes 23 are supported intermediate their ends by upright curved beams 26, the terminals 27 and 28 of which are secured to the upper and lower beams 29 and 30 of the frame 18. The tubes are connected centrally by the couplings 31 which are curved to produce the desired configuration of the radiator, the supporting beams 26 being curved to conform to the concave of the plates 13 and 14 of the shield.

The tubes 23 of the series are connected to pipes 33, the pipes being connected to con plings 32. These pipes 33, which are two in number, are disposed at both sides of the coupling 34, the curved elbows or couplings 35 connecting the couplings 32 which receive the tubes 23". It will thus be noted that the tubes are in communication and, at the same time, allow the necessary space for the coupling 34. One of the upper pipes 23 is provided with a coupling 36. A flexible connection 37 is secured to this coupling, the terminal of said connection remote from the coupling being provided with the usual air hose connection 38 whereby the same may be attached to a steam pipe 39 which is provided with a similar coupling 40. By this construction, it will be noted that steam may be supplied to the radiator, and that it will circulate through the pipes 23 and the end connecting pipes 25, completely heating the shield and maintaining it at a temperature which will melt the ice and snow, which accumulates on the track.

A backing 41 of the same configuration as the shield incloses the radiator, said backing being preferably formed of asbestos or any other non-combustible material. A metallic backing 42 is secured to the asbestos backing, the metallic backing, as well as the as bestos backing, being secured to the frame Patented Feb. 9, 1915.

This frame supports the 18. Thus, a chamber 43 is provided which concentrates the heat radiating from the tubes 23, thereby heating the plates which constitute the shield to an extent which causes the melting of the snow and ice'with which the shield contacts. The lower set of tubes 23 are provided with drain cocks 44 by means of which the condensation water H may be removed from the radiator. While the particular form of radiator illustrated has been found effectual in practice, it will be understood that the construction may be changed to meet difierent conditions.

The lower beams 30 are provided with bearings or bearing brackets 44 which consist of plates formed with the curved extensions 45, the curved extensions receiving the shafts 46 on which the wheels 47 are mounted. There are two pairs of bearings 44 disposed on the lower members 30 of the frame, the bearings of each pair of bearings being disposed at transversely opposite points on the frame in order that shafts may be arranged at the front and rear of the plow. The trucks thus formed are used in moving the plow to a position where it may be attached to the pilot of a locomotive. The backing 42 is provided with loops 48 which, when the trucks are not in use, embrace the shafts 46 adjacent the wheels which are supported thereon, thus carrying the trucks where they are readily accessible when it is desired to remove the plow from the locomotive.

The lower beams 30 of the plow frame 18 support a plurality of attaching plates 49, shown in detail in Fig. 7 These plates are formed with the oflset portions 50 which embrace the beams 30 and the apertured extensions 51. The plates are four in number, there being two arranged at transversely opposite points adjacent the front of the plow and two arranged at transversely opposite points adjacent the rear of the plow. The plates are disposed to be attached to the converging beams 52 of the pilot, there being a plurality of apertures formedvin the plates in order that the proper adjustment may be made.

In assembling the plow on the pilot, the trucks are placed beneath the bearing brackets 44 and the device rolled until it contacts with the frame of the pilot. One side of the plow is then lifted until the plates 49 engage with the upper edges of the lower portion of the pilot frame, the openings in the plates being brought into register with the openings in the pilot frame, and bolts 53 passed through the alined apertures. The other side of the plow is then raised and the plates 49 of that side attached to the pilot. The plow is then forced toward the pilot, its front end being lifted until the coupling 34 is brought into locking engagement with a corresponding coupling carried by the pilot.

The plow is then securely locked into position, being supported on the pilot and held against displacement by the coupling 35. The trucks are thenremoved and placed on the hangers 48 which are carried by the backing 42 where they are supported until it is desired to remove the plow. After the plow has been attached to the pilot, the flexible connection 37 is connected with the steam supply pipe 39 and the radiator is heated. It will be noted that in a comparatively short time the front plates of the plow will become heated to an extent which will cause them to melt the show which accumulates on the track, the engine then being allowed to pass through snow banks without danger of the snow or ice affecting the running gear.

The many advantages of a construction of this character will be clearly apparent, as it will be noted that the device may be easily and economically manufactured and that it may be conveniently attached to locomotives such as are now in use without materially altering their construction.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
